RESUMO

This article describes hematologic, nutritional, allergic/asthmatic conditions, lead screening, and management of these among immigrants and refugees. Some of these conditions present more frequently or differently in the newcomer population. Early identification and treatment are key to improving health outcomes. Screening and treatment suggested in this article are based on current guidelines and are intended for primary care providers who are caring for refugee and immigrant patients, especially within a medical home. Special considerations include level of education, instruction, demonstration, and cultural humility.

RESUMO

Multiple studies have demonstrated strong links between diet and anemia, but few have explored the impact of food groups on hemoglobin (Hb). We analyzed the correlation between Ghanaian diet and Hb levels to explore reduction of anemia prevalence through dietary interventions. Demographics, food frequency questionnaires (FFQ), and blood samples were obtained from 140 volunteers (ages 18-65) in five locations across Ghana. Hb was measured; estimated iron consumption was calculated. FFQ items were grouped by food type, and a regression analysis was performed to determine the most important dietary predictors of Hb. Moreover, 47% of total participants were anemic; 64% of females and 28% of males. Hb levels were highest in Mole (13.9 g/dL, SD = ±1.9), independent of sex distribution. The regression model revealed a 62.7% adjusted correlation between food groups and Hb levels. Animal foods (ß = 0.016, t = 5.08, p < 0.01) and plant protein (ß = 0.013, t = 2.86, p < 0.01) were the most influential groups to Hb levels. It is of vital importance to emphasize the benefits of consuming animal foods and plant proteins within the Ghanaian population. The ease of access to plant proteins makes it likely that this food group will be most influential and have the greatest impact in reduction of anemia in the Ghanaian population.

RESUMO

Hereditary spherocytosis (HS) is often misdiagnosed due to lack of specific diagnostic methods. Our study summarized clinical characteristics and described the diagnostic workflow for mild and moderate HS in Chinese individuals, using data from 20 adults, 8 of whom presented a familial history for HS. We used scanning electron microscopy (SEM) to diagnose HS. We observed reduced eosin maleimide fluorescence activity (5.50 mean channel fluorescence (MCF) units) in the 10 cases of HS, which differed significantly when compared with 10 normal adults (15.50 units), iron deficiency anemia (15.50 MCF units), and megaloblastic anemia (12.00 MCF units) values (P < .05). Next generation sequencing results revealed that 9 out of 10 patients were found to have mutations in the spectrin alpha chain (SPTB), anchor protein (ANK1), and SLC4A1 genes. These mutations were not reported in the Human Gene Mutation Database (HGMD), 1000 human genome, ExAC, and dbSNP147 databases. Splenectomy proved to be beneficial in alleviating HS symptoms in 10 cases. It was found that for the diagnosis of HS, SEM and next generation gene sequencing method proved to be more ideal than red blood cell membrane protein analysis using sodium dodecyl sulfate polyacrylamide gel electrophoresis and western blotting.

RESUMO

Children of migrant families are known to be at a higher risk of diet-related morbidities due to complex variables including food insecurity, cultural and religious beliefs, and sociodemographic factors like ethnicity, socioeconomic status, and education. Several studies have assessed the presence of specific diseases related to dietary issues in migrant children. This systematic review aims to highlight the existing body of work on nutritional deficiencies in the specific vulnerable pediatric population of immigrants. Refugees were intentionally excluded because of fundamental differences between the two groups including the reasons for migration and health status at the time of arrival. A total of 29 papers were included and assessed for quality. Most of them described a strong correlation between obesity and migration. A high prevalence of stunting, early childhood caries, iron and vitamin D deficiency was also reported, but the studies were few and heterogeneous. Food insecurity and acculturation were found important social factors (nevertheless with inconclusive results) influencing dietary habits and contributing to the development of morbidities such as obesity and other metabolic disorders, which can cause progressive unsustainability of health systems. Public health screening for diet-related diseases in migrant children may be implemented. Educational programs to improve children's diet and promote healthy-living behaviors as a form of socioeconomic investment for the health of the new generations may also be considered.

RESUMO

Since 2001, ChildFund Kenya has supplied micronutrient fortified school meals to preschoolers from two tribes (Kamba and Maasai) attending early childhood development (ECD) centres in Emali, S.E. Kenya. Lack of information on the micronutrient status of the preschoolers prompted a cross-sectional assessment of micronutrient (iron, zinc, selenium, vitamin A, vitamin D) status and prevalence of deficiencies among the two tribes. Data on sociodemographic, health, anthropometric status, and micronutrient supply from preschool meals were collected from 287 Kamba and 213 Maasai children aged 3 to 5 years attending 23 ECD centres. Nonfasting blood samples were collected for haemoglobin and plasma biomarkers of iron, zinc, selenium, vitamin A, vitamin D, C-reactive protein (CRP), α1 -acid glycoprotein, and immunoglobin G. The prevalence of anaemia was significantly higher in Maasai children than Kamba (38%, 95% CI [31%, 45%], vs. 5%, [3%, 9%]), as well as iron deficiency and its various stages (P < 0.001). No differences were seen in the prevalence of zinc, selenium, vitamin A, or vitamin D deficiencies (all P > 0.05). Body iron, CRP, and age were significant predictors of haemoglobin concentrations for both tribes (all P < 0.006) and plasma 25-OHD for Maasai children only. The higher prevalence of iron deficiency among Maasai than Kamba children was possibly attributed to the high consumption of cow's milk (low in bioavailable iron) in place of micronutrient fortified meals together with a higher prevalence of chronic inflammation and intestinal damage.

RESUMO

BACKGROUND: Which blood-based indicator best reflects the iron status in pregnant women is unclear. Better assessments of iron status in today's multiethnic populations are needed to optimize treatment and clinical recommendations. OBJECTIVES: We aimed to determine the prevalence of anemia (hemoglobin <11.0 g/dL in first and <10.5 g/dL in second trimester) and iron deficiency (ID) by the iron indicators serum ferritin <15 µg/L, serum soluble transferrin receptor (sTfR) >4.4 mg/L, and calculated total body iron <0 mg/kg, and their associations with ethnicity. METHODS: This was a population-based cross-sectional study from primary antenatal care of 792 healthy women in early pregnancy in Oslo, Norway. We categorized the women into 6 ethnic groups: Western European, South Asian, Middle Eastern, Sub-Saharan African, East Asian, and Eastern European. RESULTS: Anemia was found in 5.9% of women (Western Europeans: 1.8%; non-Western: 0-14%, P < 0.05). ID from ferritin was found in 33% (Western Europeans: 15%; non-Western: 27-55%, P < 0.05). ID from sTfR was found in 6.5% (Western Europeans: 0.3%; non-Western: 0-20%, P < 0.01). Calculated total body iron indicated ID in 11% (Western Europeans: 0.6%, non-Western: 7.0-28%, P < 0.01). The prevalence of ID was significantly higher by all measures in South Asian, Sub-Saharan African, and Middle Eastern than in Western European women, and the ethnic differences persisted after adjusting for confounders. South Asians, Sub-Saharan Africans, and Middle Easterners had lower iron concentrations by all measures for all hemoglobin intervals. Anemia related to ID varied from 35% (sTfR) to 46% (total body iron) and 72% (ferritin) depending on the iron indicator used. CONCLUSIONS: Women at the highest risk of ID and anemia were of South Asian, Middle Eastern, and Sub-Saharan African origin. The prevalence of ID differed considerably depending on the iron indicator used.

RESUMO

The diet of the Indigenous Sami people has become more Westernized. The lack of population-based data on nutrient intake and nutritional adequacy, in combination with a high prevalence of obesity/metabolic syndrome among Sami, was the rationale behind the present study. We hypothesized that differences in nutrient intake between Sami and non-Sami populations may still exist but that these differences are likely small, especially with respect to nutritional contributors to cardiometabolic health. We used cross-sectional data from the SAMINOR 2 Clinical Survey (2012-2014) to study nutrient intake, assessed by a food frequency questionnaire, in 2743 non-Sami, 622 multiethnic Sami, and 1139 Sami participants aged 40-69 years. We applied quantile regression to study ethnic and inland/coastal regional differences. The median intake of most nutrients met the Estimated Average Requirements of the 2012 Nordic Nutrition Recommendations. However, the average intake of saturated fatty acids and sodium was higher, and average intake of fiber was lower than recommended, regardless of ethnicity and geographic region. The diet of Sami vs non-Sami participants and participants from the inland vs coastal region contained significantly more iron and vitamin B12. We found a number of statistically significant ethnic differences in nutrient intake; however, many of these differences were small (3%-4%). We observed no ethnic disparities in nutritional adequacy between Sami and non-Sami populations living in rural Northern Norway. Our results suggest that, compared to the non-Sami, the Sami have a dietary intake that may reduce their risk of iron deficiency but not their cardiometabolic risk.

RESUMO

Iron deficiency anemia is a major public health problem among pregnant women in developing countries. This study aimed to use a randomized controlled trial to evaluate the effectiveness of a health information package in Jordanian anemic pregnant women's knowledge regarding anemia, compliance with iron supplementation, and hemoglobin level. Two hundred pregnant anemic women were recruited and randomly assigned into intervention or control group from April to July 2016. The intervention group received a video presentation of the Health Information Package Program (HIPP), narrated by a midwife, combined with PowerPoint slides to educate women about anemia in pregnancy. The participants in the control group received standard care in antenatal clinics, including iron supplementation. No significant differences were observed between the groups in age, gestational age, health problems, and total income. Only education and source of information differed significantly between the groups. Women in the intervention group had higher scores on the compliance checklist, knowledge, food selection ability, and hemoglobin level than women in the control group. The health information package program was effective. Policymakers should adopt a health information package program and apply it as a comprehensive national strategy for the prevention of anemia during pregnancy.

RESUMO

: Obesity in pregnancy may negatively influence maternal and infant iron status. The aim of this study was to examine the association of obesity with inflammatory and iron status in both mother and infant in two prospective studies in pregnancy: UPBEAT and SCOPE. Maternal blood samples from obese (n = 245, BMI ≥ 30 kg/m²) and normal weight (n = 245, BMI < 25 kg/m²) age matched pregnant women collected at approximately 15 weeks' gestation, and umbilical cord blood samples collected at delivery, were analysed for a range of inflammatory and iron status biomarkers. Concentrations of C- reactive protein and Interleukin-6 in obese women compared to normal weight women were indicative of an inflammatory response. Soluble transferrin receptor (sTfR) concentration [18.37 nmol/L (SD 5.65) vs 13.15 nmol/L (SD 2.33)] and the ratio of sTfR and serum ferritin [1.03 (SD 0.56) vs 0.69 (SD 0.23)] were significantly higher in obese women compared to normal weight women (P < 0.001). Women from ethnic minority groups (n = 64) had higher sTfR concentration compared with white women. There was no difference in maternal hepcidin between obese and normal weight women. Iron status determined by cord ferritin was not statistically different in neonates born to obese women compared with neonates born to normal weight women when adjusted for potential confounding variables. Obesity is negatively associated with markers of maternal iron status, with ethnic minority women having poorer iron statuses than white women.

RESUMO

BACKGROUND: Iron deficiency remains a prevalent adolescent health problem in low income countries. Iron supplementation is recommended but improvement of iron status requires good adherence. OBJECTIVES: We explored factors affecting adolescent adherence to weekly iron and/or folic acid supplements in a setting of low secondary school attendance. METHODS: Taped in-depth interviews were conducted with participants in a randomised, controlled, periconceptional iron supplementation trial for young nulliparous women living in a rural, malaria endemic region of Burkina Faso. Participants with good, medium or poor adherence were selected. Interviews were transcribed and analysed thematically. RESULTS: Thirty-nine interviews were conducted. The community initially thought supplements were contraceptives. The potential benefits of giving iron supplementation to unmarried "girls" ahead of pregnancy were not recognised. Trial participation, which required parental consent, remained high but was not openly admitted because iron supplements were thought to be contraceptives. Unmarried non-school attenders, being mobile, were often sent to provide domestic labour in varied locations. This interrupted adherence - as did movement of school girls during vacations and at marriage. Field workers tracked participants and trial provision of free treatment encouraged adherence. Most interviewees did not identify health benefits from taking supplements. CONCLUSIONS: For success, communities must be convinced of the value of an adolescent intervention. During this safety trial, benefits not routinely available in iron supplementation programmes were important to this low income community, ensuring adolescent participation. Nevertheless, adolescents were obliged to fulfil cultural duties and roles that interfered with regular adherence to the iron supplementation regime. TRIAL REGISTRATION: Trial Registration at clinicaltrials.gov : NCT01210040.

RESUMO

BACKGROUND: Elevated serum uric acid (SUA) involved in iron metabolism, has been increasingly recognized as a risk factor for gout and cardiovascular diseases. The objective of this study was to examine the associations between markers of iron status with risk of hyperuricemia (HU) in Chinese adult population. METHODS: Data were extracted from the 2009 wave of the China Health and Nutrition Survey, consisting of 7946 apparently healthy adults. Serum ferritin (SF), transferrin, soluble transferrin receptors (sTfR), hemoglobin (Hb), high-sensitivity C-reactive protein (hs-CRP), and SUA were measured. Diet was assessed with three consecutive 24 h recalls. Demographic characteristics, smoking status, alcohol consumption, and physical activities were investigated using a structured questionnaire. Multilevel mixed-effects models were constructed to estimate the associations of SF, transferrin, sTfR, and Hb with SUA and the risk of HU. RESULTS: The crude prevalence of HU was 16.1%. SF, transferrin, and Hb levels were positively associated with SUA and the risk of HU after adjustment for cluster effects and potential confounders (all p-trend < 0.05). Compared with participants in the lowest quartile of SF, those in the highest quartile had significantly higher SUA concentrations (ß = 0.899 mg/dL, 95% confidence interval (CI): 0.788, 1.010; p < 0.001) and higher risk of HU (odds ratio (OR) = 3.086, 95% CI: 2.450, 3.888; p < 0.001). Participants with the highest quartile of transferrin had significantly higher SUA concentrations (ß = 0.488 mg/dL, 95% CI: 0.389, 0.587; p < 0.001) and higher risk of HU (OR: 1.900; 95% CI: 1.579, 2.286; p < 0.001) when compared with those with the lowest quartile. In male participants, those in the highest quartile of Hb had significantly higher risk of HU when compared to the reference group (OR: 1.401, 95% CI: 1.104, 1.777; p < 0.01); however, this association was not found in female participants (OR: 1.093; 95% CI: 0.821, 1.455; p = 0.544). CONCLUSION: SF, transferrin, and Hb levels were positively associated with the risk of HU, and additional studies are needed to confirm the findings, as well as to elucidate their underlying mechanisms.

RESUMO

PURPOSE: The aim of this study is to examine the co-occurrences of low serum ferritin and zinc and anaemia among mothers and their children in two agro-ecological zones of rural Ethiopia. METHODS: Data were collected from 162 lactating mothers and their breast fed children aged 6-23 months. The data were collected via a structured interview, anthropometric measurements, and blood tests for zinc, ferritin and anaemia. Correlation, Chi-square and multivariable analysis were used to determine the association between nutritional status of mothers and children, and agro-ecological zones. RESULTS: Low serum levels of iron and zinc, anaemia and iron deficiency anaemia were found in 44.4, 72.2, 52.5 and 29.6% of children and 19.8, 67.3, 21.8, 10.5% of mothers, respectively. There was a strong correlation between the micronutrient status of the mothers and the children for ferritin, zinc and anaemia (p < 0.005). Deficiency in both zinc and ferritin and one of the two was observed in 19.1, and 53.7% of the mothers and 32.7 and 46.3%, of their children, respectively. In the 24 h before the survey, 82.1% of mothers and 91.9% of their infants consumed foods that can decrease zinc bioavailability while only 2.5% of mothers and 3.7% of their infants consumed flesh foods. CONCLUSION: This study shows that micronutrient deficiencies were prevalent among lactating mothers and their children, with variation in prevalence across the agro-ecological zones. This finding calls for a need to design effective preventive public health nutrition programs to address both the mothers' and their children's needs.

RESUMO

Ferritin is a universal intracellular protein that acts as an iron carrier. Several studies have indicated that iron deficiency affects thyroid function in non-pregnant women. Our objective was to assess the relationship between serum ferritin levels and thyroid function in pregnant women during the second trimester. Pregnant women with sufficient iodine intake and normal antithyroid antibodies during the second trimester were recruited from the obstetric outpatient department of the Fifth People's Hospital of Fudan University. Serum ferritin (SF) levels, thyroid function, anti-thyroid antibodies and vitamin B12 were determined by electrochemiluminescence immunoassay kit. Maternal serum iron (Fe), unsaturated iron binding capacity (UIBC), hemoglobin (Hb), creatinine (Cr), fasting blood glucose (FBG), and alanine aminotransferase (ALT) were also evaluated. Stepwise regressions performed to evaluate the associations between SF and other maternal parameters. In the second trimester, 11.4% pregnant women had a SF concentration less than 12 µg/L, and 7.6% pregnant women were anemic. SF levels were negatively correlated with serum TSH levels (r = -0.219, p < 0.05), and positively correlated with FT4 levels (r = 0.203, p < 0.05). Linear regression analysis showed only SF, age, week of gestation were significant predictors of regression with TSH as the dependent variable (ß: -0.007, -0.059, and 0.118 respectively; all p < 0.05). However consistent relation between the SF levels and FT4 was not observed in stepwise linear regression. Maternal iron status is a determinant of TSH concentrations during pregnancy in pregnant women during the second trimester.

RESUMO

Inappropriate complementary feeding, both in quantity and quality, is a major determinant of undernutrition. However, little is known about how infant-caregiver's feeding behaviours affect infants' energy intake. Therefore, the objective of this study was to characterize infant-caregiver feeding behaviours and investigate their association with infants' energy intake. The study involved 106 mother-child pairs recruited from seven randomly selected kebeles of Mecha district, West Gojam, Ethiopia. The feeding styles were assessed through observations of 1-day, in-home, feeding episodes that were videotaped and coded into self-feeding, responsive, active, distracting, and social feeding behaviours. Infants' haemoglobin and anthropometric measurements were taken. The association between feeding behaviour scores and energy intake per meal was investigated. The mean food intake of the infants was very low (11.4 ± 7.0 g/kg body weight per meal) compared to the minimum theoretical gastric capacity (30 g/kg body weight per meal). Infants' haemoglobin concentration was negatively associated with energy intake (ρ = 0.178, p = .03). Infants' responsive and active positive feeding styles were positively associated with energy intakes (ρ = 0.258 and 0.432, p = .004 and p < .001, respectively) as well as caregivers' responsive positive feeding styles (ρ = 0.237, p = .007). Both haemoglobin concentrations and feeding styles were associated with infant's energy intake. Anaemia prevention and control measures should be reinforced. Current nutrition education programmes should give emphasis on ways to effectively incorporate culturally adapted responsive feeding messages in this and similar settings.

RESUMO

BACKGROUND: The prevalence of iron deficiency anaemia (IDA) rises with age. Migrants are potentially at higher risk for IDA because of differences in intake and uptake as well as their higher comorbid status. We assessed whether geriatric Turkish and Moroccan migrants have a higher prevalence of low iron status and IDA. METHODS: Retrospective case-control study in a geriatric outpatient clinic (2012-2015). In total, 188 consecutive Turkish and Moroccan migrants aged ≥ 65 years were included and matched with 188 Dutch controls. Matching was based on the visiting date of the patients. Main outcome measures were serum ferritin level (below 15 µg/l) and IDA. IDA was defined as anaemia according to the WHO definition, with a serum ferritin level below 15 µg/l and serum CRP below 10 mg/l. Multivariate logistic regression was performed to correct for confounders. RESULTS: Mean serum ferritin level was significantly lower in migrants (83.46 µg/l, SD 106.8 vs. 164.94 µg/l, SD 160.1, (p < 0.05)). In total, 7.4% met the IDA criteria, of these 5.6% were migrants and 1.8% were Dutch (p < 0.05). After correction for age, gender, BMI, and use of NSAIDs, a low ferritin level was associated with migrant status (OR 3.0, 95% CI 1.0-8.9) as was IDA (OR 2.9, 95% CI 1.2-7.2). CONCLUSION: Prevalence of low serum ferritin and IDA is increased in the first-generation Turkish and Moroccan geriatric migrant population. This might be caused by differences in iron intake or uptake from nutrition between the populations or because of gastrointestinal pathology; further study is warranted.

RESUMO

BACKGROUND: Iron deficiency, the most common micronutrient disorder and cause of anaemia globally, impairs growth, cognition, behaviour and resistance to infection. METHODS/RESULTS: As part of a national survey of inherited haemoglobin variants in 7526 students from 72 secondary schools purposefully selected from the 25 districts of Sri Lanka, we studied 5912 students with a normal haemoglobin genotype. Median age was 16.0 (IQR 15.0-17.0) years and 3189 (53.9%) students were males. Most students were Sinhalese (65.7%), with fewer Tamils (23.1%) and Muslims (11.2%). Anaemia occurred in 470 students and was more common in females (11.1%) than males (5.6%). Haemoglobin, serum ferritin, transferrin receptor and iron were determined in 1196 students with low red cell indices and a structured sample of those with normal red cell indices (n = 513). The findings were weighted to estimate the frequencies of iron deficiency and iron deficiency anaemia classified according to WHO criteria. Iron depletion (serum ferritin <15ug/ml) occurred in 19.2% and cellular iron deficiency (low serum ferritin and transferrin receptor >28.1 nmol/l) in 11.6% students. Iron deficiency anaemia (cellular iron deficiency with low haemoglobin) occurred in only 130/2794 (4.6%) females and 28/2789 (1.0%) males. Iron biomarkers were normal in 83/470 (14.6%) students with anaemia. In multiple regression analysis, the odds for iron depletion and cellular iron deficiency were about one-third in males compared with females, and the odds for iron deficiency anaemia were about one fifth in males compared to females. Tamil ethnicity and age <16 years increased the risk of all three stages of iron deficiency and living at high altitude significantly reduced the risk of iron depletion. CONCLUSIONS: Low iron status and anaemia remain common problems in Sri Lankan secondary school students especially females, younger students and the socioeconomically disadvantaged Tamil population. More research is needed to identify factors other than low iron status that contribute to anaemia in adolescents.

RESUMO

Background: African Americans are at increased risk of iron deficiency (ID) but also have higher serum ferritin (SF) concentrations than those of the general population. The Hemochromatosis and Iron Overload Screening (HEIRS) Study was a multicenter study of ethnically diverse participants that tested for the hemochromatosis (HFE) C282Y genotype and iron status.Objective: We sought to determine the prevalence and predictors of ID (SF concentration ≤15 µg/L) and elevated iron stores (SF concentration >300 µg/L) in HEIRS women of reproductive age (25-44 y).Design: The HEIRS Study was a cross-sectional study of iron status and HFE mutations in primary care patients at 5 centers in the United States and Canada. We analyzed data for women of reproductive age according to whether or not they were pregnant or breastfeeding at the time of the study.Results: ID was present in 12.5% of 20,080 nonpregnant and nonbreastfeeding women compared with 19.2% of 1962 pregnant or breastfeeding women (P < 0.001). Asian American ethnicity (OR ≤0.9; P ≤ 0.049) and HFE C282Y (OR ≤0.84; P ≤ 0.060) were independently associated with a decreased risk of ID in nonpregnant and nonbreastfeeding women and in pregnant or breastfeeding women. Hispanic ethnicity (OR: 1.8; P < 0.001) and African American ethnicity (OR: 1.6; P < 0.001) were associated with an increased risk of ID in nonpregnant and nonbreastfeeding women. Elevated iron stores were shown in 1.7% of nonpregnant and nonbreastfeeding women compared with 0.7% of pregnant or breastfeeding women (P = 0.001). HFE C282Y homozygosity had the most marked independent association with elevated iron stores in nonpregnant and nonbreastfeeding women and in pregnant or breastfeeding women (OR >49.0; P < 0.001), but African American ethnicity was also associated with increased iron stores in both groups of women (OR >2.0; P < 0.001). Asian American ethnicity (OR: 1.8; P = 0.001) and HFE C282Y heterozygosity (OR: 1.9; P = 0.003) were associated with increased iron stores in nonpregnant and nonbreastfeeding women.Conclusions: Both ID and elevated iron stores are present in women of reproductive age and are influenced by ethnicity and HFE C282Y. Efforts to optimize iron status should keep these findings in view. This study was registered at clinicaltrials.gov as NCT03276247.

RESUMO

INTRODUCTION: Iron deficiency anemia is the most common worldwide nutritional deficiency contributing to childhood morbidity and mortality. According to the official health policy in Israel, providing iron for all babies from the age of 4 months to the age of one year old is recommended. This policy also recommends providing iron supplementation for an additional 6 months for toddlers (who are one year old) with anemia (hemoglobin<11mg/dl). Despite this policy, there is still a high rate of anemia in the Negev's two year old children, especially in the Bedouin population. OBJECTIVES: Assessment of the intervention program to reduce iron deficiency anemia rates, that provides iron supplementation to Bedouin toddlers with no anemia, from the age of 1 year to 18 months and maternal knowledge about the prevention of anemia. METHODS: Type of Research: Community intervention trial study. Population study: A total of 251 toddlers aged one year old with no anemia from 6 recognized and unrecognized Bedouin villages. Intervention group: 250 toddlers who received iron supplementation; Prophylactic dosage (15 mg per day) for 6 months from the age of 1 year. Control group: 101 toddlers who did not receive iron supplementation. The hemoglobin (Hb) level was measured before and after the intervention for both groups. RESULTS: At the beginning of the study, at the age of one year there was no difference between the two groups in the average Hb level (11.8±0.5mg/dl). After the intervention of 6 months, an Hb decrease was observed in both groups: 11.5±0.8 mg/dl compared to 11.0±1.0 mg/dl in the intervention group and in the control group (p<0.001), respectively. At the study endpoint the rates of anemia in the intervention group were lower compared to the control group: 40.6% and 15.3% (p<0.001), respectively. A positive correlation was found between the toddlers Hb level and the amount of iron supplementation received through the study. CONCLUSIONS: Providing iron supplementation, from the age of 1 year for 6 months reduces the anemia risk during the second year of life. We suggest changing the recommendation to continue iron supplementation for toddlers (beyond one year old) only for children with anemia to a new policy and propose continuing iron supplementation beyond one year old to all toddlers at this age.

RESUMO

BACKGROUND: Micronutrient deficiencies are still highly prevalent in countries undergoing the nutrition transition, but nationally representative data documenting their burden in children are exceedingly rare. OBJECTIVE: To examine the distribution and recent trends in micronutrient status biomarkers of Colombian children. METHODS: We compared the distributions of plasma ferritin, serum zinc, and vitamin A in Colombian children between 2005 and 2010 using 2 cross-sectional, nationally representative surveys overall and by categories of sociodemographic variables. Analysis for ferritin included boys and nonpregnant girls aged 1 to 17 years. Analyses for zinc and vitamin A included children aged 1 to 4 years. RESULTS: The mean 2010 to 2005 differences in ferritin, zinc, and vitamin A were 2.5 µg/L (95% confidence interval [CI]: 1.3 to 3.7), -34.9 µg/dL (95% CI: -39.6 to -30.2), and -11.5 µg/dL (95% CI: -12.3 to -10.7), respectively, after adjusting for sociodemographic characteristics. These differences varied significantly by region of residence. In 2010, region of residence was a significant correlate for all 3 micronutrients. Other important correlates included age and maternal education for ferritin and body mass index-for-age Z score, maternal education, wealth index, food insecurity, and urbanicity for vitamin A. CONCLUSIONS: Plasma ferritin was slightly higher in 2010 than in 2005, whereas serum zinc and vitamin A were substantially lower in 2010. In the absence of obvious causal explanations, it is uncertain whether this decline represents a worsening of micronutrient status in Colombian children or an artifact due to systematic laboratory or data management errors incurred in the surveys.

RESUMO

The aim of this study was to assess the effect of vegetarian diet on iron metabolism parameters paying special attention to serum hepcidin and soluble transferrin receptor (sTfR) concentrations in 43 prepubertal children (age range 4.5-9.0 years) on vegetarian and in 46 children on omnivorous diets. There were no significant differences according to age, weight, height, and body mass index (BMI) between vegetarian and omnivorous children. Vegetarians had similar intake of iron and vitamin B12 and a significantly higher intake of vitamin C (p < 0.05) compared with non-vegetarians. Hematologic parameters and serum iron concentrations were within the reference range in both groups of children. Serum transferrin levels were similar in all subjects; however, ferritin concentrations were significantly (p < 0.01) lower in vegetarians than in omnivores. In children on a vegetarian diet, median hepcidin levels were lower (p < 0.05) but sTfR concentrations significantly higher (p < 0.001) compared with omnivorous children. In the multivariate regression model, we observed associations between hepcidin level and ferritin concentration (ß = 0.241, p = 0.05) in the whole group of children as well as between hepcidin concentration and CRP level (ß = 0.419, p = 0.047) in vegetarians. We did not find significant associations with concentration of sTfR and selected biochemical, anthropometric, and dietary parameters in any of the studied groups of children. As hematologic parameters and iron concentrations in vegetarians and omnivores were comparable and ferritin level was lower in vegetarians, we suggest that inclusion of novel markers, in particular sTfR (not cofounded by inflammation) and hepcidin, can better detect subclinical iron deficiency in children following vegetarian diets.
